Controlliamo il portafiltro e il gruppo erogatore.

Controlliamo comes from the verb controllare, meaning to check, to inspect, or sometimes to verify.

In this sentence, controlliamo most naturally means we check or let’s check, depending on context.

So it can function as:

• we check the portafilter and the brew group
• let’s check the portafilter and the brew group

Italian often uses the same form for both we do and let’s do.

In Italian, the 1st person plural form can be used both:

• as a normal statement: we check
• as a suggestion or inclusive command: let’s check

So controlliamo can be:

• Noi controlliamo... = We check...
• Controlliamo... = Let’s check...

Usually, the situation tells you which meaning is intended. In instructions, demonstrations, or spoken guidance, let’s check is often the best translation.

Italian often leaves out subject pronouns because the verb ending already shows who the subject is.

Here, -iamo tells you the subject is we.

So:

• Controlliamo il portafiltro...
• Noi controlliamo il portafiltro...

both mean the same thing, but the version without noi is more natural in most contexts.

It is the present indicative, 1st person plural of controllare.

Breakdown:

• infinitive: controllare
• stem: controll-
• ending for noi in -are verbs: -iamo

So:

• io controllo = I check
• tu controlli = you check
• noi controlliamo = we check / let’s check

Italian normally repeats the article before each noun when listing two separate things.

So:

• il portafiltro e il gruppo erogatore

means:

• the portafilter and the brew group

Repeating the article sounds natural and clear in Italian. In some cases Italian can omit the second article, but here repeating il is the standard choice.

Literally, portafiltro is made of:

• porta- = carrier/holder
• filtro = filter

So the literal sense is filter holder.

In coffee-machine language, it usually means the portafilter, the handled part that holds the coffee basket and locks into the espresso machine.

Gruppo erogatore is a technical coffee-machine term.

• gruppo = group, unit, assembly
• erogatore = dispensing/delivery unit, something that dispenses

In espresso-machine context, gruppo erogatore usually refers to the brew group or group head, depending on the machine and context.

It is the part involved in delivering water through the coffee.

Here it functions like a noun used in combination with another noun.

• gruppo = the main noun
• erogatore = specifies what kind of group/unit it is

So gruppo erogatore is a compound-style technical expression, something like dispensing unit or brew group.

Italian often forms technical terms this way.

Yes. E simply means and.

So:

• il portafiltro e il gruppo erogatore
• the portafilter and the brew group

A pronunciation note: e is pronounced like eh, not like the English letter name ee.

Because the sentence is talking about checking the portafilter and the brew group as individual parts.

Italian uses the singular just as English does here:

• the portafilter
• the brew group

If it meant several of them, you would expect plurals such as:

• i portafiltri
• i gruppi erogatori

Yes, very naturally.

In instructional or training contexts, Controlliamo il portafiltro e il gruppo erogatore often works like:

• Let’s check the portafilter and the brew group
• Now we check the portafilter and the brew group

Italian frequently uses noi forms in explanations, tutorials, and demonstrations to guide the listener through a process.

A helpful approximation is:

con-trol-LYAH-mo

A few details:

• gli is not present here, so don’t overcomplicate it
• the ia in -iamo sounds like yah
• the stress falls on -ia-: controlLIÀmo

So the ending -iamo is very common and worth learning well.

Not really. The order is very straightforward and typical for Italian:

• verb + object(s)

So:

• Controlliamo = we check / let’s check
• il portafiltro e il gruppo erogatore = the two things being checked

This is a very standard sentence structure and a good model to remember.
